Check Digit Verification of cas no

The CAS Registry Mumber 211043-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,0,4 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 211043-68:
(8*2)+(7*1)+(6*1)+(5*0)+(4*4)+(3*3)+(2*6)+(1*8)=74
74 % 10 = 4
So 211043-68-4 is a valid CAS Registry Number.
